Thou Shalt not Bear False Witness Against Your Customers: Cultural Norms and the Volkswagen Scandal
Iftekhar Hasan, Felix Noth, Lena Tonzer
Abstract
This paper investigates whether cultural norms shaped by religion drive consumer decisions after a corporate scandal. We exploit the unexpected notice of violation by the US Environmental Protection Agency in September 2015, accusing the car producer Volkswagen (VW) to have used software to manipulate car emission values during test phases. Using a difference-in-difference model, we show that new registrations of VW (diesel) cars decline significantly in German counties with a high share of Protestants following the VW scandal. Our results suggest that the enforcement culture rooted in Protestantism affects consumer decisions and penalises corporate fraud.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Journal of Banking and Finance,
2018
Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a feedback loop leading into default as a transitory state for all but the very worst ratings. We use a bivariate semiparametric dynamic panel model to reproduce the joint dynamics of sovereign ratings and government bond yields. The individual equations resemble Pesaran-type cointegration models, which allow for valid interference regardless of whether the employed variables display unit-root behavior. To incorporate most of the empirical features previously documented (separately) in the literature, we allow for different long-run relationships in both equations, nonlinearities in the level effects of ratings, and asymmetric effects in changes of ratings and yields. Our finding of a single good equilibrium implies the slow convergence of ratings and yields toward this equilibrium. However, the persistence of ratings is sufficiently high that a rating shock can have substantial costs if it occurs at a highly speculative rating or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

The Euro Plus Pact: Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Journal of Common Market Studies,
No. 3,
2015
Abstract
The Euro Plus Pact was approved by the European Union countries in March 2011. The pact stipulates various measures to strengthen competitiveness with the ultimate aim of preventing accumulation of unsustainable external imbalances. This article uses Granger causality tests to assess the short-term linkages between changes in relative unit labour costs and changes in the current account balance for the period 1995–2011. The main finding is that changes in the current account balance precede changes in relative unit labour costs, while there is no discernible effect in the opposite direction. This suggests that capital flows from the European core to the periphery contributed to the divergence in unit labour costs across Europe prior to the global financial crisis. The results also suggest that the measures to restrain unit labour costs may have only limited effect on the current account balance in the short term.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
In the present paper, we build a bivariate semiparametric dynamic panel model to repro-duce the joint dynamics of sovereign ratings and government bond yields. While the individual equations resemble Pesaran-type cointegration models, we allow for different long-run relationships in both equations, nonlinearities in the level effect of ratings, and asymmetric effects in changes of ratings and yields. We find that the interest rate equation and the rating equation imply significantly different long-run relationships. While the high persistence in both interest rates and ratings might lead to the misconception that they follow a unit root process, the joint analysis reveals that they converge slowly to a joint equilibrium. While this indicates that there is no vicious cycle driving countries into default, the persistence of ratings is high enough that a rating shock can have substantial costs. Generally, the interest rate adjusts rather quickly to the risk premium that is in line with the rating. For most ratings, this risk premium is only marginal. However, it becomes substantial when ratings are downgraded to highly speculative (a rating of B) or lower. Rating shocks that drive the rating below this threshold can increase the interest rate sharply, and for a long time. Yet, simulation studies based on our estimations show that it is highly improbable that rating agencies can be made responsible for the most dramatic spikes in interest rates.

The Euro Plus Pact: Cost Competitiveness and External Capital Flows in the EU Countries
Hubert Gabrisch, K. Staehr
Abstract
The Euro Plus Pact was approved by 23 EU countries in March 2011 and came into force shortly afterwards. The Pact stipulates a range of quantitative targets meant to strengthen cost competitiveness with the aim of preventing the accumulation of external financial imbalances. This paper uses Granger causality tests and vector autoregressive models to assess the short-term linkages between changes in the relative unit labour cost and changes in the current account balance. The sample consists of annual data for 27 EU countries for the period 1995-2012. The main finding is that changes in the current account balance precedes changes in relative unit labour costs, while there is no discernible effect in the opposite direction. The divergence in unit labour costs between the countries in Northern Europe and the countries in Southern and Eastern Europe may thus partly be the result of capital flows from the core of Europe to the periphery prior to the global financial crisis. The results also suggest that the measures in the Euro Plus Pact to restrain the growth of unit labour costs may not affect the current account balance in the short term.

Local Economic Structure and Sectoral Employment Growth in German Cities
Annette Illy, Michael Schwartz, Christoph Hornych, Martin T. W. Rosenfeld
Tijdschrift voor economische en sociale geografie,
No. 5,
2011
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on sectoral employment growth in German cities (“urban growth”). We test four elements simultaneously – sectoral specialisation, diversification of economic activities, urban size and the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. Our regression results show a U-shaped relationship between localisation economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former, a U-shaped relationship is found, whereas the effect is inversely U-shaped for the latter.

Trade Misinvoicing: The Dark Side of World Trade
A. Buehn, Stefan Eichler
World Economy,
No. 8,
2011
Abstract
We analyse the determinants of trade misinvoicing using data on 86 countries from 1980 to 2005. In a simple microeconomic framework, we derive the determinants of four different types of trade misinvoicing taking into account that only the financial incentives determine whether and how much exports/imports to underinvoice or overinvoice, whereas the deterrents only affect the extent of misinvoicing. The hypothesised determinants are tested using data on discrepancies in bilateral trade with the United States. We find that the black market premia and tariffs motivate illegal trading activities. Higher financial penalties effectively act as a deterrent to this crime.

Is East Germany Catching Up? A Time Series Perspective
Bernd Aumann, Rolf Scheufele
Post-Communist Economies,
2010
Abstract
This article assesses whether the economy of East Germany is catching up with the West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as unemployment rates, wage rates and production levels in the manufacturing sector. In contrast to existing studies of convergence between regions of the reunified Germany, our approach is based purely upon the time series dimension and is thus directly focused on the catching up process in East Germany as a region. Our testing set-up includes standard ADF unit root tests as well as unit root tests that endogenously allow for a break in the deterministic component of the process. We find evidence of catching up for East Germany for most of the indicators. However, the convergence speed is slow, and thus it can be expected that the catching up process will take further decades until the regional gap is closed.

Specialization, Diversity, Competition and their Impact on Local Economic Growth in Germany
Martin T. W. Rosenfeld, Annette Illy, Michael Schwartz, Christoph Hornych
Abstract
This study systematically examines the impact of fundamental elements of urban economic structure on urban growth in Germany from 2003 to 2007. We test four elements simultaneously, that is sectoral specialization, diversification of economic activities, urban size as well as the impact of local competition. To account for the effect of varying spatial delimitations in the analysis of urban growth, we further differentiate between cities and planning regions as geographical units. The analysis covers manufacturing industries as well as service sectors. Most previous work produces inconsistent results and concentrates on localization economies and/or diversification, while urban size and the effect of local competition are widely ignored. Our regression results show a U-shaped relationship between localization economies and urban growth and positive effects of local competition on urban growth. With respect to diversification, we find positive effects on urban growth on the city-level, but insignificant results on the level of the planning regions. The impact of urban size also differs between free cities and planning regions; in the former a U-shaped relationship is found whereas the effect is inversely U-shaped for the latter.
